Abstract
The amount of elongation of a workpiece during forging can be determined by image processing to calculate the total amount of horizontal movement of marked patterns such as forging scale on the ends of the workpiece which move away from a forging bite during the forging blow. Images of marked patterns before and after a forging blow on both sides of the bite of a forging die are compared to determine the movement of the marked patterns and thus the movement of the ends of the workpiece. A method and system of determining the elongation and vertical displacement of a workpiece during forging is disclosed.
